Connected it to a SimNet network (Nmea2000) and plugged the USB into my computer. This gave the traffic on the network except for AIS communication.
From the Actisense manual I learned that there are two varients of the NGT-1-USB:
1. Standard
2. AIS version
I had the standard. Fortunately, the difference is only in the firmware and I was able to update to the AIS version by downloading from the Actisense website.
